 30 THE CONDOR VOL. X throat and fore chest also black? sides of head and neck, patch on chest bordering black area behind, and median abdominal region, dull white; whole back -(includ- ing scapulars and rump) and sides, flanks, and crissum, pure smoke gray, without any of the buffy cast characterizing Parus gambeliambeh; wings and tail mouse gray, edged with lighter. MASVRaTS OF TYF.--Length (of skin), 132 min.; wing, 72.5; tail, 66; tarsus, 19; depth of bill, 4; culmen, 10.5. DmRBVOT.--The mountains of southern California (breeding in the Tran- sition and Boreal zones), and adjacent valleys in winter. REMARKS.--The characterization of this new subspecies is based upon an ex- amination of 95 skins of Parus gambeli. Thirty-six of these were loaned me by the United States National Museum, thru Dr. C. W. Richmond, Acting Curator, Division of Birds. The remaining 59 are from my own collection, and include 46 from southern California all of which are fairly referable to Parus gambeli baileyre. Forty-seven skins from northern California, Oregon, Washington, and Rocky Mountain region from New Mexico and Arizona to Montana, are all Parus gam' beh' gambeli. One skin from Fort Tejon and others from Mount Whitney and further north in the Sierra Nevada are plainly P. g. gambeli. Two skins from Mount Pinos, Ventura County, are indeterminate, one being juvenal, and the other a worn adult. The'race baileyre is larger and grayer than the northern and Rocky Mountain race gambeli. These characters are altogether constant in fully adult birds. An occasional baileyre in first annual plumage has the sides not as clearly gray, being faintly overcast with brownish, and so is like gambeli. But the bulklet bill then serves as a criterion for recognition. I believe I would have no trouble in assort- ing even immatures of the two races. I take pleasure in naming this well-marked new chickadee for Mis. Vernon Bailey (Florence Merriam Bailey), whose accurate and pleasantly-written accounts of many of our birds form an important component of the ornithology of the west. Pasadena, Cahf ornia NOTES FROM THE DIARY OF A NATURALIST IN NORTHERN CALIFORNIA a By JOHN F. FERRY HE following notes were made while carrying on field-work in northern Cal- ifornia for the U.S. Biological Survey, under the direction of C. Hart Mer- riam, during the summer and autumn of 1905. The writer was associated from July 21 to August 9 with Mr. A. Sterling Bunnell, then a medical student in the University of California, and from September 18 to November 3 with James H. Gaut, at that time a regular employee of the Survey and a field-worker of much experience. i, Author's Note: This article is written from notes as they were jotted down in a field diary, and at the time served merely as memoranda from which extensive reports were sent in from each locality visited No effort was made to identify material in the field. as such material, including mammals birds and plants, was seut in with field data only.' Hence the article must lack in completeness and thoroness, but still a conscientious effort has been made to keep out of error and to make positive assertions only when they are justified. Credit is given to others whenever possible. Altitudes were taken by two aneroid barometers. I am indebted to the Biological Survey for a number of edenti- fications as noted in the text.
